From the patents it’s look Nikon is actively working their own version of DPAF sensors and sooner or later we will have new breed of Nikon sensors in upcoming Mirrorless cameras.
From patents (Translated)
To provide a focus detection device with which it is possible to detect a focus with high accuracy without being affected by color of light.SOLUTION: A focus detection device comprises: a phase difference detection unit for detecting phase difference by using a plurality of first pixels for outputting a pair of first signals corresponding to the luminous amount of a first color, a plurality of second pixels for outputting a pair of second signals corresponding to the luminous amount of a second color, and phase difference in the pair of first signals, or the pair of second signals; and a defocus amount calculation unit for calculating a defocus amount by using a first coefficient corresponding to the first color when the phase difference is detected by using the pair of first signals, and calculating a defocus amount by using a second coefficient corresponding to the second color when the phase difference is detected by using the pair of second signals.
